SAFETY-LANTERN FOR VARNISHERS OF BREWERS VATS.

SPECIFICATION forming part 0f Letters Patent No. 409,007, dated August 13, 1889.

Application filed February 26, 1889. Serial No. 301,237. (No model.)

To @ZZ whom t may concern:

u' Beit known that I, VILLIAM BREGLER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Safety-Lanterns for Varnishers of Brewers Vats, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a safety-lantern that is adj ustably suspended outside a brewers vat when its interior is being varnished in such a position that the light through a tube secured to said lantern is projected through the man-hole of said vat into its interior to light up the same while the varnisher works, to avoid the danger resulting from the presence of a light within thevat of the ignition of the varnish and of the volatile combustible gases that emanate therefrom; and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a vertical section of the vat and shows the relative position of the suspended safety-lantern as respects said vat. Fig. II is an enlarged side view of the suspended lantern, with part broken away, to show the lighted lamp and the concave disk that refleets the light through the illuminating-tube. It also shows the adjustable means of suspension of saidlantern. Fig. III is a horizontal section taken on line III III, Fig. II, and shows the interior of the lantern, the illuminating-tube, and the glasses in said tube through which the light shines. Fig. IV is an enlarged detail of the top of the bail, and shows the loop at its summit that engages on the lug that projects from the suspensoryhanger pin from which the lantern is suspended. Fig'. V is an enlarged View o1' the suspensory hanger, and shows its pivotal attaching-screw in full and broken lines in va- -rious adjustable positions to change the position of the lantern and the direction in which its illuminating-tube is presented. Fig. VI is a vertical section taken on lines Vl VI, Fig. V, and shows the lug on the rear end of the pivotal attaching-screw engaged in the slot in the side of the suspensory hanger to hold the screw in its intermediate angular position; and Fig. VII is a vertical section of the suspensory hanger, taken on line VII VII, Fig. V.

Referring to the drawings, l represents a brewer-s vat in connection with which my safety-lantern 2 is used, and 3 is the man-hole .in the vat by which the operator enters to eifect the varnishing of said vat and in which the illuminating-tube 4: that proj eets from the lantern is inserted.

5 represents the suspensory hanger, which is preferably a square metal tube that has a clear opening 6 along most or all of its length on one side and at one end, and also around said end at the opposite side for a sufficient distance to allow the pivotal working of the head of the attachment-screw. lVithin the said tubular hanger the pivotal end of the adj ustable attachment-screw 7 is seated so as to allow the hanger from which the lantern is suspended to both slide on the head of the screw that supports it and 4to turn on its pivots hereinafter described.

The hanger is provided with an elongated slot S on its upper side, in which slot travels the pivot-pin 9, that ascends from near the rear end of the attaching-screw, and which pivot-pin travels back and forth along the slot 8 as the attachment-screw is moved along the hanger-tube or said hanger on the pivoted head of said screw. The elongated slot S in the hanger-tube may also, if desired, be duplicated along the bottom side of the hanger, in which case the pivot-pin is also duplicated on the lower side of the head of the attachmentscrew and travels in the lower slot as the upper pin does in the upper slot. The tubular hanger can thus be freely slid along on the 'pivoted head of the attachment-screw and said screw also be turned on its pivot to adjust the position of the lantern that is suspended from said hanger, as' will be hereinafter described.

The attaching-screw has a screw-threaded point 10, which, when the hanger is to be placed in position, is screwed intot-he outside of the vat at l1, just sufiiciently above the man-hole for the lantern when suspended from the hanger to present the illluminat-ing-tube in said man-hole.

12 represents a square or rectangular lug that projects from the rear end of the pivotal attaching-screw, and when said screw-head IOO has been moved to about a half-way intermediate position along the rectangular tubular suspcnsory hanger and turned on its pivot 9 to a right angle with said hanger the said lug l2 enters and is seated in the rectangular slot 13 in the back of said suspensory hanger, so as to steady it in that position and re-enforce its hold from turning. (See Fig. 5,)

An extension flat lug lt that projects from the outer end of the suspensory hanger pro vides a seat for the loop l5 at the summit of the bail 16, which bail is secured to the safetylantcrn beneath by bolts or rivets 17. A keypin 1S, that is seated in the perforation 10 near the outer end of the flat lug, holds the loop that surmounts the bail ot' the lantern on its suspensory seat, and 2O is a chain that holds said key-pin captive, being secured thereto and to the staple 2l, that surmounts the outer end of the suspensory hanger, so

that the key-pin may not be mislaid when itA is lifted at times that it is desired to remove the lantern.

The lantern 2 maybe constructed ol brass, tin, or any other suitable sheet metal, and is preferably made, as shown in Fig. lll, wide at the rear to increase its reflective capacity, and taperingtoward the front to concentrate the rays of light toward the telescopic tube that conveys said light through the man-hole into the interior of the vat.

lVhile, as stated, I prefer to construct said lanterns thus tapering toward the front, yet I do not confine myself to that shape, for any other convenient construction may be used that would be adaptable for the attachment of the telescopic ray-transmitter and other elements described above and below that provide the sole means for the transmission of the innocuous rays of light that said combustion generates within the vat unaccompanied by the dangerous inflammable adj uncts ol' said combustion.

2i? represents hanger-rings that are secured by riveted straps 23 to near the top ot the back ol the lantern for hanging it up against a partition or wall, or in any other suitable position, when it is not suspended from the suspensory hanger, and loops 24F., which are secured to the back of the lantern near the bottom, may also be used as a coadjutory means for securely holding the lautern when it is not suspended by the bail 1G.

25 represents the door in the back of the lantern, which door is secured thereto by the hinges 2G, and 27 are perforatious through the back plate of the lantern below the door, to ventilato the same.

JS represents the lamp within said lantern, which is held down to its seat by elongated lugs 29, that are secured on the inside of the sides of the lantern. The lamp is preferably provided with a twin jet-burner 30, the jets of which are ranged in the position shown in Figs. ll and Ill, so as to individually throw the rays of light through the illuminating expansive tube to the best advantage to disseminate said light in the interior of the vat. A concave retlectingdisk 3l reflects the light from the rear of the lamp to eombinewith the direct rays therefrom in lighting up the interior of the vat.

32 represents a flanged shoulder or collar that projects from the `front plate of the lan-- tern, an d is located around the orifice through which the light is thrown, and stay or latch pins project from each side of said collar.

rlhe illuminating-tube i is furnished at its inner end with a surrounding telescopic collar 34, which projects at the rear longitudinally Afrom the tube it incases, and is provided with bayonet joint angleslots 35, which engage on the stay-pins Ifllfand when said collar is turned part around, as shown in Fig. II, the pins and slots in said collar constitute abayonet-joint to hold and lock the illuminating-pipe to the flanged collar ol' the lantern. The minor glass disk 3G is placed inside the telescopic collar 234-, abutting agai ust the illummating-tube, and when said collar is seated on the langed collar 32 and locked thereto by the bayonet-joints the glass disk is thus held to its seat.

37 represents the flaring expansive forward collar of the illuminating-tube, secured or flanged from the forward end of which is the ring-collar 3S, projecting from each side of which are the stay-pins 3f).

t() represents a cap-collar, and 4l an inwardly-projecting flange therefrom, which collar and lange incase the major glass disk 42. Th e collar 40 is provided with two bayonetfjoint angle-slots 43, which, when said collar is telescoped on the collar 3S, embrace the stay-pins 3), and when slightly turned, as shown in Fig. II, the said collars are locked together and securely hold the major glass disk in its seat.

4A represents the surinounting smokelluc of the lantern, a cap 45 on the top of which is provided with vents yl-G around the top ol' its collar and a perforated disk-top t7. A diametrically-enlarged tubular cap 4S has au inwardly-flanged rim tf), that fits over the cap 45, and said cap is provided with. circular and angular perforations 50 around near the top thereof, and is surmounted by a disk 51, to prevent the too free escape of sparks from the lantern.

It is well known that there is great danger to the operator and to the vats bein g varnished when lanterns are, as has been the usual practice, taken in bythe operator when he enters through the man-hole into the interior of the vat and varnishes the same.

The very inilammable nature of the material he is using and the volatile combustible gases that arise therefrom results i u great danger of ignition of the gases and material and of a consequent explosion. The danger is also increased by droppings from the varnish falling on the heated lantern.

My safety-lantern is devised to avoid all these contingent dangers, and at the same IOO time has ineans provided for convenient adjustable suspension, thus allowing the operator full freedom to attend to the work of varnishing without the necessity of a divided continuous attention to the lantern that light-s up his work. i

-The operation of the suspension and adjustment of the lantern is as follows: Supposing the attachment-screw 7 to be in the position shown in full lines in Fig. V, its point longitudinally in line with the suspensory-hanger tube 5 and projecting therefrom, as shown, before the attachment of the device to the vat. Now, run the attachmentscrewlongitudinally back (the pivot pin or pins 9 that project from the head of said attachment-screw running back freely in the slot or slots 8 in the suspensory hanger) until the projecting lug 12 at the rear of the pivoted head of said attachment-screw is on line with the slot 13, near the middle of the rear side of the hanger. Now, turn the screw around, as shown in broken lines half-way along' said hanger and projecting at a right angle therefrom, the same turning readily on its pivot pin or pins 9, and the lug 12, that projects from the rear of the screw-head, is then seated and held in the slot 13 in the rear side of said hanger. Now, it will be seen that when the suspensory-hanger tube and its pivotally adjustable and sliding attachmentscrew are brought into their above-stated respective positions, the hanger serves as a handle for operating the gimlet-pointed screw, while the operator is inserting it at 11 in the head of the vat, suitably located and adjacent to the man-hole7 so that the lantern that is suspended from the hanger throws its light through said man-hole. Now, the screw having been, as stated, firmly secured in the head of the vat, the hanger is turned on the pivot pin or pins on the head of said screw back at a right-angle positionto that described above until the lug 12 is thus released from the slot 13 in the rear side of said hanger, and the hanger is then outdrawn longitudinally into the position from which I started in my operative description, in which the screw is shown in full lines on longitudinal line with said hanger, the pivot-pin 9 having been freely run along the elongated slot to its terminal position at the inner end of the hanger. Now, the hanger is turned round to the reverse angle position to that already described, (shown in detail in broken lines in Fig. V,) the head of the attaching-screw being then projected through the short opening on the reverse side of the hanger to that from which it projects at the time of the insertion of its screw-point in the head of the vat. The loop 15 of the bail 16 of the lantern is then seated on the projecting flat lug 14, that extends from the outer end of the suspensory hanger, the lantern thus being suspended therefrom, and the captive key-pin 18 is inserted outside said bail to securely hold it on its seat. The lantern is now lighted ready for operation, except that when thehanger is thus folded back against the head of the vat the lantern is out of the way of the man-hole, and its illuminating-tube is not presented in line to dispense its light throughsaid man-hole into the vat to be illuminated while the operator varnishes the same, but, being swung out of the way, the said opening is free for the operator to enter through it into the interior of the vat with his varnish pot and brush. The operator then swings around the suspensory hanger and the lantern that hangs pendent therefrom into the position shown in Figs. I and V, so that the rays of light are thrown directly within the vat, which is brightly illuminated thereby, without the great danger of ignition that sometimes results from the practice of varnishing when the light is within the vat. Vhen it is desired to throw the light on an incline to the one side or the other, itis evident that by a slight deviation of the position of the suspensory hanger, by swinging it on its pivot pin'or pins 9, the same can be accomplished. The flaring mouth of the illuminating-tube never reaches within the vat, so that the droppings of the varnish cannot readily alight on said tube or any other part of the hot lantern and thereby cause explosions. Vhen the operator has completed his work, he swings the hanger and the suspended lantern around to the position described before he entered the vat, which leaves the man-hole open for him t-o pass through, and he then can proceed with the lantern and varnish to the next vat to be operated on. The usual plug stops the man-hole when it is placed therein. 1

I claim as my invention 1. In a safety-lantern for varnishers of brewers Vat-s, the combination of the suspensory tubular hanger, from which the lantern is suspended, the adjustable pivoted screwattacher of said hanger, and the stay-lug 12, that projects longitudinally from the head of said screw-attacher and engages in the slot 13 on the rear side of said tubular suspensory hanger to steady the head of the screw in its intermediate position, substantially as de` scribed, and for the purpose set forth.
